I'd rather the NFL add a minor league football farm system than expand.

Absolutely this. If the NFL wanted to follow Rain Man's model, I'd love to see it play out that way.

You think fans currently don't give a shit about the Kansas City Chiefs and the Jacksonville Jaguars? Wait until they come across the El Paso Desperados and the Riverside Douchebag Hipsters.

Take those new garbage teams that nobody wants and make them feeder teams. Fans in those cities will have an incentive to care about the players on those teams because a bunch of them will turn into stars at the pro level, which is why it won't falter like the XFL or UFL. Also, since the NFL is the money giant it is, that organization won't go broke either or run out of money.
